Esau used a question to emphasize that eating was more important than a birthright. This can be translated as a statement. AT: "My inheritance is no good to me if I die of hunger!" (See: [[rc://en/ta/man/translate/figs-rquestion]])
What Jacob wanted Esau to swear can be stated explicitly. AT: "First swear to me that you will sell me your birthright" (See: [[rc://en/ta/man/translate/figs-explicit]])
